so for example, if I wanted a worker that will just do a API call each 5mins, would fetch be the one I use?

You would want cron triggers, and the scheduled handler

Scheduled Handler · Cloudflare Workers docs

When a Worker is invoked via a Cron Trigger, the scheduled() handler handles the invocation.

hmmm I see I see

alan•2/28/24, 10:54 PM

is there an easy way for me to get the current memory footprint of my worker?

i have a memory sensitive application that i'm hoping to be able to attach logs to

alan•2/28/24, 10:54 PM

or maybe i should be posting on the help page?

Isaac McFadyen•2/29/24, 12:07 AM

There's no way, unfortunately.

FISK•2/29/24, 12:17 AM

Does workers free tier have any limitation on concurrency, e.g how many instances of a single worker can run at once?

Isaac McFadyen•2/29/24, 12:26 AM

~~No.~~ Sort of.

Isaac McFadyen•2/29/24, 12:27 AM

You may be rate-limited if you request Workers too quickly, however. Let me see if I can find the docs.

Isaac McFadyen•2/29/24, 12:27 AM

https://developers.cloudflare.com/workers/platform/limits/#burst-rate 1000 requests per minute on Free.

Santosh•2/29/24, 12:34 AM

In case of smart placement, would the request still be routed thru Pops to the Worker location?

Isaac McFadyen•2/29/24, 1:49 AM

Yes, it's routed internally on the Cloudflare network.

Unsmart•2/29/24, 3:03 AM

No, you can only use workerd

Isaac McFadyen•2/29/24, 3:38 AM

(which is what is used in the production Cloudflare Workers environment)

Old Man Maker•2/29/24, 8:32 AM

Thanks - I finally found it. It isnt at the end, but is written as a weird CNAME record with the R2 identifier of it. I think it would just make more sense to keep all the CF records in a seperate list under the traditional DNS records?

Old Man Maker•2/29/24, 8:34 AM

Hi - I'm not quite groking HONO

I am attempting to write an image into an R2 bucket - but the HONO request body returned is not happy

        const body = await c.req.parseBody();
        c.env.R2_MY_BUCKET.put('test.png', body);

        const body = await c.req.parseBody();
        c.env.R2_MY_BUCKET.put('test.png', body);

Type 'BodyData' is missing the following properties from type 'ReadableStream<any>':..........

Any assist?

zegevlier•2/29/24, 10:21 AM

If you astro site is static, it can already run completely for free.

PPatrick Star Not if you enable the adapter, which is required for the image pipeline.

Hello, I’m Allie!•2/29/24, 10:39 AM

Then it isn’t static, no?

Hello, I’m Allie!•2/29/24, 10:40 AM

Also, aren’t image transforms applied at build time anyway, unless you use SSR?

Hello, I’m Allie!•2/29/24, 10:43 AM

I mean that, by default, doesn’t Astro use sharp during build, which then allows the entire shebang to be served statically?

Hello, I’m Allie!•2/29/24, 10:43 AM

Even the images?

Hello, I’m Allie!•2/29/24, 10:44 AM

You don’t need the Image Service if all of the images are pre-generated

PPatrick Star Rezising etc is useful

Hello, I’m Allie!•2/29/24, 10:45 AM

Yes, but if the dimensions of the image are available at build time, then you are wasting cycles resizing images on the fly

JJoeDoe Is there a limit to how long a worker can run?

Hello, I’m Allie!•2/29/24, 10:59 AM

30 seconds of CPU time, and theoretically indefinite runtime, though it may be evicted after 30 seconds

JoeDoeOP•2/29/24, 11:00 AM

oh cpu time is quite different from actual time right?

JoeDoeOP•2/29/24, 11:00 AM

I need my worker to get some data, but the initial 'sync' might take like 10mins+

JJoeDoe oh cpu time is quite different from actual time right?

Hello, I’m Allie!•2/29/24, 11:02 AM

CPU time is time that your Worker is actually doing something. For example, streaming a request to your origin is not counted as CPU Time, but hashing the request body is

JoeDoeOP•2/29/24, 11:03 AM

perfect should be fine then

JJoeDoe perfect should be fine then

Hello, I’m Allie!•2/29/24, 11:04 AM

Though note that 10 minutes might be stretching the limits there. I wouldn’t say it won’t ever work, but I would be wary of expecting it to work every time

vakno•2/29/24, 11:09 AM

I have a parent worker that has service bindings with two child workers that change HTML responses using HTMLRewriter. I want changes that these 2 workers make all applied to the trigger url of parent worker. I cant seem to figure out how to combine responses.
Any help would be appreciated.

so for example, if I wanted a worker that will just do a API call each 5mins, would fetch be the one
